To all whom it may concern.-

Be it known that I PERLEY R. Grass, a citizen of the United States, residin at Quincy, in the county of Norfolk and State ofiassachusetts have invented an Im rovement in Lasting-Machines, of which t e following description, in connection with the. accompanying drawings, is a specification, like tlsetters onthe drawings representing like par My invention relates to lasting machines and will be best understood by reference to the following description when taken in connection with the accompanying illustration showing one specific embodiment thereof, while its scope will be more particularly pointed out in the appended clalms.

In the drawings,---Fi re 1 shows in front elevation a lasting macine embodying one term of my invention; Fig. 2 is a vertical central sectional view partially broken away, and on an enlarged scale, showin the rincial working parts in the heel an toe code; i ig. 3 is a section on the line 3-4? in Fi 2 showi the toe post clamp; Fig. 4L is a p an view on the same enlarge scale showing that end of the machine which carries the toe head; Fig. 5 is a lan oi the remainder of the machine inclu ing the part carrying the heel head; Fig. 6 is a plan showing the t reference to a jacked shoe, and with certain parts removed to show the details ofthe wipers; Fig. 7 shows, in plan, the heel carria o with parts removed to illustrate thedetai s of the heel band; Fig. 8 is a section in elevation, of the line 8-8. in -Fig. 2

and looking toward the end of the machine; Fi. 9 is a section in elevation and on a sti further enlarged scale taken centrally and longitudinallythrough the heel head and showing the principal working arts thereof; Fig. 10 is a rear end view 0 the heel head on the same scale as Fig. 9; Fig. 11 is a detail artially in section showing on an enlarged scale certain of the heelband-clamping levers; Fig. 12 is an enlarged detail showing the toothed sectors for moving the toe head; F. 13 is a transverse section on the line 13-13 in Fig. 1 looking toward the toe head, showing the machine on a somewhat largerscale; Fig. 1a is aplan hand wheel 5.

view in partial section, taken on the line 14-14, in Fig. 13; Fig. 15 is a section on the line 15 -15, in Fi 1 1, looking toward the slidin clutch mem er; Fig. 16 1s a view of the sli ing clutch member and the swinging actuator looking up from beneath the same, and Fig. 17 is a transverse section in elevation, similar to that of Fig. 13, but looking in the opposite direction toward the heel head.

Referring to the drawings and to the embodiment of my inventionthere illustrated, the mainframe A Fig. 1) of the machine is suitably supports and formed to provide a bed for the oppositely disposedtoe and heel carriages B and C, respectively, which latter are provided with suitable lasting devices for o crating u onthe shoe to be lasted, the bee carriage carrying also suitable means for presenting the shoe to the lasting devices and for releasing the same after asting, as will be fully described.

Referring, first, more particularly to the toe head, the same comprises (Figs. 1, 2 and 8) a rest I) horizontall fixed, but,.as here after described, vertica ly movable, the said rest having formed thereon suitable guideways lengthwise the machine, along which is slidably mounted the appropriately formed base 0 of the toe carriage, t e same being retained in its guideways by overlying ibs b (Fig. 8). J ournaled in the rest and eld against longitudinal movement is the adjusting screw 6 having threaded engagement with the nut 0 (Fig. 2) upon the carriage base and provided outside of and beyond the extended end of the rest with a By means of the hand wheel the. operator can adjustably advance the carriage lengthwise the machine to or from the work.

Both the heel and toe carriages are provided (Figs. 4c, 5 and 6) with similarly constructed and arranged pairs of wiper plates 6!, to which are remova 1y secured appropriately shaped wiper jaws d, the wi er plates being covered by the protecting p ate a! 1n Fi t and 4, which latter is removed in Fig. 6 or sake of clearness. Each plate is rovided with the pair of guiding slots d and (1 respectively the walls of which on age with longitudinal REISSUED ly alined upright gui ing rolls Wiper carrier 6 d and a3, journaled in the wiper carrier, which latter in the toe carriage is designated by e and in the heel carriage by f.

The slots are so shaped and ositioned with reference to the rolls that t e wipers are caused to undergo a combined swmging and sliding movement. This is such that the forward-movement of the plates causes the jaws to move bodilyforward and at the same time to swing in and close about their inner adjacent median ed es, which latter are maintained continua y in contact to effect the usual wiping of the leather upon the shoe S undergoing lasting, without causing wrinkling or marring of the leather between the wiping plates.

Each wiper is connected for forward movement about the guiding rolls by an underlying link (2 attached to the shding guide block (i (Flgs. 2, 6 and 8) slidably mounted in overlying beveled guideways (Fig. 8) for lon itudmal movement in the eneath the wiper lates. This connection of the plates to the s iding actuator or guide block provides a very compact construction requiring but small space, so that, when retracted, the plates ig. 4) which are of a general rectangular.

formation, conform to the general outline of the carriage top.- The block (i has jointed thereto the lever d one end of which has a relatively 'fixed fulcrum upon the wiper carrier at d", the opposite end having the handle grip d. B means of this handle the operator at w' can move the guide block lengthwise the carrier, causing the.

wiper jaws to close in toward or open and release from the jacked shoe, as will be clear from Fig. 6.

The handle grip upon the lever attached to the toe carriage has the overlying thumb piece a? forming part of a lever, which latter is fulcrumed at 61 and carries at its opposite end a pawl or catch (i sprin -pressed to engage with the teeth of the underlying stationary rack 03 secured to the side of the wiper carrier, the teeth of the said rack being inclined to permit the toe wiper plates to be temporarily held in any position to which they may be inwardly moved. Similar means for holdin the heel wipers in position may be emp oyed but not' being ordinarily required such means are not here shown.

In order that the wiper jaws may be quickly removed or replaced by others of different attern each one is held in a split or recess 1n the edge (Fig. 2) of the plate d firmly held against dis lacement duri use, each jaw can be readily withdrawn aberally and forwardly b merely removing the single retaining pm 5 Both the heel wipers and the toe wipers are mounted to permit their adaptation to different pitches or inclinations of the last lengthwise the machine, the adjustin means beingFsubstantially the same for bot carriages. or this purpose the toe wiper carrier e and the heel wiper carrier f are each 'adjustably mounted upon the respective main carriage bodies 9 by means of transversely disposed trunnions g (Fi s. 2 6 and 13) fixedly held near the forwar en of the carriage body and journaled in lugs vupon the Wiper carrier, whereby the latter is pivotally mounted for adjustment about a transverse axis. Each wiper carrier (Figs. 2, 9 and 10) has depending at its rear a toothed segmental portion 9 which meshes with a worm 9 the latter connected to a small upri ht hand wheel 9*, journaled in the carriage Eody g and projecting up and through the rear of the carriage so as to be conveniently accessible to the operator for quickly adjusting the inclination of the wipers. By the .use of the worm and the Worn gear segmerit, there is provided means, not only for a delicate adjustment, but for an effectual locking of the parts when the hand wheel is released. The carriage in each case forms a box or shell-like com artwipers to different inclinations len thwise the last, they may also be rocked or a justed laterally to different inclinations transversely of the last. For this purpose the lower front and rear walls of the main carria e body (Figs. 7, 9 and 10) are provided wit flanged and transverse curved segmental bearing portions g, which are slidably mounted in correspondingly curved guideways formed in the carriage base, the toe carriage base being designated by 0 and the heel carriage base by h. The stationary segmental gibs g overlie the flanged hearing portions and prevent all movement of the carriage body upon the base except a sliding, rocking movement, which, owin to the'curvature of the bearing portions and the guideways, takes lace about an exis passing through the line of action of the wiper jaws w en the latter are in a mean or horizontal lane, a displaced position of the carriage, or example, being shown in dotted lines in F' 10.

To permit the described adjustment, each carria e base (Figs. 7, 8 and 9) at its rear has crumed to it the link g, which latter as a friction device to prevent the accidental is connected to the depending end of a segmental beveled gear 9, pivoted or journaled .upon the carriage body and meshing with the beveled pinion g which is secured to one end of the upwardly and rearwardly inclined shaft 9 The latter is inned or otherwise secured to the rearward y projecting hand wheel 9 (Fig. 1) by which the segmental gear may beturned and the carriage body swung or forced to one side or the other upon the curved guideways about its connection to the link 9 as a fulcrum, this operating, as is evident, adjustably to tip or rock the wiper .jaws laterally.

- Where the shaft 9 asses throu h the walls of the carriage bo y (Fig 9) t ere is provided a cylindrical cup or pocket containing the compression sprin g which presses outwardly against the oose washer g and causes it frictionally to engage the washer fastened to the hand wheel 9 to retard t e movement'of the parts. This acts displacement of the carriage body from its ad usted position upon the curved guide-' ways. The washers may be of cast iron or any other suitable friction material, such as leather or the like, to increase this retardation.

The adjustment of the wiper plates described is substantially the same for both the heel and the toe carriages, and the wiper plates themselves upon the two carriages, except for the shape of the attached jaws, may

be, and herein are, of substantially the same construction.

Referring more particularly to Figs. 2 and 3 and to the toe carriage there shown, the

latter is provided at the fore-part thereof (Figs. 1, 2, 4: and 13) with a vertically slidable toe 0st 2', mounted in the upright post support 1/, the latter carried u on a bracket which is clamped to the front ace or wall of the carria e base a. The upper end of the post is for ed to formears, between which is pivotall mounted the padded toe rest t the curved ace of which, preferably centered at the ivot, is covered with leather or other suita lecushioning'material t and adapted to underlie the toe of the jacked shoe, as

, shown in Fig. 2. The rest is normally moved to an upright position by the upward pressure received from the hea of a springpressed pin i engaging the flattened lower end of the rest between the forked ears. Any tendency to relative movement, how- I ever, between the leather of the shoe and the contacting rest, whether due to the stretch of the leather or slight movements of the jacked shoe, permits the rest to be rolled or swung more or less about its ivot from the normal position, to adapt itself to the changed position of the leather without straining or marrfing the same. The poet is prevented from turningby a threaded stud z" in the post support, which enga es with a groove lengt wise the post. A ter the shoe is jacked, the

toe rest is raised in its support and pressed against the underlying leather of the toe.

For this purpose, the post at its bottom is secured to a sliding rest 6, which latter is supported loosely u on the fiat top of a swinging shelf 2' w llCll, Fig. 4, is pivoted at i to the frame of the machine, but which by mechanism to be described can be swung up and down at appropriate times to raise and lower the shoe and its attached toe rest. To adjustably vary the limits of vertical movement of the toe post, the lower end thereof is s lit (Figs. 2 and 3), being suitably formed to embrace a tongue. 2' which is formed upon the upper side of the sliding rest 6. The tongue and the upper face of the rest a ainst which the lower edges of the toe post a ut, are inclined to form a wedgeshaped cam. The toe post is provided with a clamping screw to clam the split lower end securely to the tongue 2. When adjustment of the toe post is desired, it is unclam ed and after the slide is moved forward? or backward sufficiently to give the desired adjustment to the post, the latter is again clamped in position.

Referring again to the toe carriage (Figs. 1 and 2), the rest I), which supports the carriage base and the wiper parts, is vertically adjustable to permit relatlve vertical movement between the wiper jaws and the jacked shoe. For this (purpose the rest is carried upon upright ro s 7' (Figs. 1, 2 and 8) which are guided for vertical sliding movement in a part 5; of the frame, the lower ends of the rods being connected to the cross-head j, to which is secured the vertical and appropriately guided actuating rod j". The latter (Figs. 12, 13 and 14:) carries at its lower end the double faced rack j", the opposite faces of which mesh respectively with the toothed se ents j and 7 The segment j (Fig. .14 is fast to the horizontal shaft 7', which carries at its outer end, conveniently located 'with reference to the position of the oper-.

ator, the foot treadle j", downward pressure upon which acts to move the segment and raise the rack, actuating rod and toe carriage. This movement 18 performed at the beginning of the toe lasting, the wipers at the same time being moved inwardly by the hand lever d to engage the leather at the sides of the toe and Wipe it up and over the sides of the toe. The wipers are then moved inwardl over the insole to wipe the leather in and own over the same. During the latter operation the weight of the toe head alone may be relied upon to press the wipers down and-against the leather overlying the insole, but I have also here provided a second and separate foot lever j, connected to 1 if it a shaft 9' which is secured to the segment 7', before referred to, whereby pressure upon the said foot lever i vmay act in addition to the weight of the toe head to force the wipers down.

Vertical tension springs (Fig. 13) are secured at their upper en s to the framework and at their lower ends to the crosspiece 9', fast upon the plunger-rod j, the said sprin thereby actlng to counterbalance a portion of the weight of the toe head, whereby the effort required to raise the same is reduced. A brace 7' connected to the cross-head j assists in supporting the outer end of the rest I).

Referring more particularly to the heel carriage, the base It thereof is provided w th pairs of rollers h (Figs. 9 and 10), wh1ch engage with suitably formed horlzontal guide-ways formed on the inside of the horizontal frame extension A and upon which the heel carriage with its attached ack 0st may be freely moved lengthwise the be of the machine and toward or away from the toe carriage.

The jack post (Figs. 2, 9 and 17) has a pin pivoted at is between the forked ears of a threaded stud H, the latter adjustably threaded into and through the upper end of the vertically slidable sleeve 70 which sleeve is carried for slidin movement in the post support is. The sprlng-pressed pin is having a flat head bearing against the lower edge of the pivoted pin 70 is provided in the threaded stud to normally maintain the pin in an upright position, while permitting the same to yield slightly from that position.

The sleeve is? is horizontally rigid, that is,

non-swinging, and the post therefore having no rocking movement, except as permitted by the pin,.is adapted to give the shoe firm support. Within the sleeve is and protruding from the lower open end of the latter, is the interior heel post rod 7c, the lower protruding end of which is cut away at one sideto carry the revoluble guide roller is, which latter is adapted to contact with the inclined face of the wedge or cam-shaped guide shoe is, the said shoe being mounted for adjustable movement lengthwise the bed of the machine in the bracket k clamped or otherwise secured to the carriage base It for movement therewith. The rod k is vented from turnin within the sleeve by means of threaded pins engaging ooves lengthwise the rod, and the sleeve k is similarly prevented from turning within the post support by the pin is, shown in dotted lines Fig. 9.

The post is freely slidablein a'vertical direction under the control of the cam shoe alone, no other supporting medium being here employed, and, since the cam afl'ords an unyielding support for the sleeve It and the of the cam plate, permitt' pro-- with the curved sleeve an unyielding support for the shoe, the latter is held in its lasting position without danger of slippage.

A last having been placed upon the heel pin 70, the 0st is then caused to move upward and ackward to seat the counter of the shoe firmly into the heel band. For this purpose the post sup ort la is attached to a slide is, which is s 'dable lengthwise the heel carriage base (Fig. 10) in grooved ways k Compression springs k (Fig. '9) encircling parallel longitudinal rods k, the latter passing throu h the slide, normally tend to force the sli e and its post forward and away from the heel band. The slide, however, may be retracted against the compression of these springs by means of the link is, jointed at its rear end to the vertically swinging lever is" (Fig. 10), the latter secured to the transverse carriage shaft is, journaled in the carria e base. To the outer end of the shaft is astened a large hand wheel is, by turning which the operator can retract the slide through the connections described.

The inner face of the hand wheel is provided (Figs. 5 and 10) with a series of ratchet teeth is which are adapted to engage with a transversely slidin pawl 70 the latter slidably mounted in a racket k fixed to the side of the carriage base. The pawl carries a depending pin working in a slot in the bracket and provided with a roller is, the latter adapted to contact with the inner face of a lon 'tudinal cam ide k and retract the paw when the bee carriage is moved to its outer position, such for example, as is shown in Figs. 1 to 5, thereby leavin the springs is free to return the toe post s ide forward when the hand wheel is released.

When .the shoe is jacked, the operator gives the hand wheel a partial turn in a lefthand direction, this serving to raise and retract the post and seat the counter of the shoe in the heel band. With the same movement of the hand the carriage is pulled forward on its rollers toward the toe carriage and into some such position as is shown in Fi 2. In passing to this osition the pawl ro is passes oflf the roun ed front e In" the pawl to engage the ratchet teeth on t e hand wheel and hold the latter in the position to which the operator has turned it, thereby efiectuall locking the shoe in its jacked and retracted position. On the subsequent reversemovement of the carria after the shoe has been lasted, as will be escribed, the hand wheel and Gflack post slide are automaticall releas by the engagement of the paw roll out eggs of the cam plate, which causes withdraw of the pawl from the ratchet teeth of the wheel. The jack within suitab e limits by severe L ost slide is therefore automatically unlocked y the carriage movement and without the need of additlonal controllin levers to require the special attention of t e operator.

The retraction of the 0st su port causes (Fig. 9 the ost roller 1 to ri e up the inclined 'ace 0 .the cam shoe is from the position shown in Fig. 9 approximately to the osition shown in Fig. 2, the jacked shoe bem thereby elevated during its retraction to but up against the slightly overlying under ed es of the wiper jaws.

he jack in la is vertically adjustable ga ement of the stud la in the sleeve It, a co nut F1025 being employed to lock the pin in its adjusted position. The height to which the ack ost is elevated may be varied log adjusting t e inclined face of the cam s oe lengthwise the carriage. To edect this the lower edge of the cam shoe is toothed and meshes with a seental gear 70 journaled in the bracket 9 and having secured thereto, but outside of the bracket. (F igs. 1 and 10) the short lever arm is", by which the gear may be turned and the shoe adjusted to diderent positions, its position being fixed by the en a ement of a spring-pressed pin It carrie t ereby with a sense of depressions formed in the outer face of the bracket.

The heel carriage is positioned and locked in its forward or advanced position by the catches Z'(Figs. l and 5) secured at appropriate positions on either side of the frame ed and adapted to en age each with aswinging latch Z, which atches are secured to opposite ends of a transverse shaft Z 'ournaled in the forward part of the carriage ase, the said latches being normally thrown down to engage each its res ective catch by the tension spring (Fig. 1 Z encircling the said shaft. The latch Z nearest the operator is rovided with the handle 1*, by.

means of w ich "manual release of the carria e may be efiected at any desired time,

an said latch has also the forwardly projecting ear Z through which the carriage is automatically released, as will hereafter be described.

During lasting it is desirable to exert additional pressure to press the last u and against t e wipers and particularly mani ulation of the heel wi ers. To permit t is there is provided (Figs. 14 and 17) a foot treadle is fulcrumed to the frame, and adapted to elevate the lifting rod which latter is normally depressed by the spring k. The upperend of the rod is.

guided (Fig; 5) in a bracket is arranged transverse 'te frame so as to permit the rod Figs. 9, 10 and 17 when elevated to pass t rough a vertically drilled lug it in the bracket k and at the-side of the shoe It.

the threaded en uring cling the rod m etween t When the shoe is jacked and elevated against theheel band and the carriage forwardly posltioned, the lower end of the post rod In", which overhangs the side of the'cam shoe is brought mto approximate alinement with the lifting rod so that elevation of the latter forces the shoe up and a ainst the wiper jaws with a pressure whic may be regulated by theoperators foot pressure on the treadle 70. bring the heel not only into the heel band i The heel band (Figs. 7 and 9) has the pad m of leather or other suitable material and of suitable and suficient depth and length. Th1s ad is secured, as by wiring, stitching or ot er suitable means, to the-relatively narrower strip of flexible sprocket chain We outside of the same. The pad at its outer end is supported and stifi'ened by the longitudinal exteriorly fastened rods or strips m, the rear ends of which are twisted to present a flattened face to the under side of the wiper carrier to which they are secured by screws, which pass through slots in the flat tened faces, so that the strips permit the pad to move forward or back or to open expansively without ofiering resistance, while still supporting and preserving the form of the same.

At the rear the ad and sprocket chain are supported by the bracket or block m", which is clamped to the under side of the sprocket chain. The block is supported by attachment to the cross-piece m which is mounted for a limited slidin movement len thwise the machine (Fig. .u on the stu s m screwed into the front en of the wi er carrier.

fter the shoe has been seated in the heel band, the ends of the latter are caused to press inwardly and forwardly firmly against the counter to hold the shoe for action by the wipers. For this purpose the last link at each end of the sprocket chain has pivoted to it the donnection mf, which is adjustably secured by the rearwardly and outwardly inclined connectin turn buckle m to an arm of the yoke m, t e latter Fig. 9) being swiveled at its center upon t 'e stud m vertically screwed into the head at carried at the forward end of the rod m, the latter slidably mounted in and lengthwise the wiper-carrying plate.

When the yoke is slid forward, by. reason of its connections to the pad it forces the pad endsinwardly and forwardly causing the pad to firmly clamp the-counter of the shoe. When the yoke 1s retracted, the

ad is o ened for the release of the shoe. Thelma m and the yoke carried thereby are normally retracted to open the pad by means of the com ression s ring m encirhe front wall of the wi er plate and a collar m the latter secure to the rod.

f the pad. and causes the cross-piece m to seat agamst the wiper-carryingplate. In ackin the shoe the operator simultaneously ro ls the carriage forward into the lasting osition indicated in Fig. 2, where it is ocked as described. There is then set in motion oweractuated means which act both to tighten the heel band and raise the toe pad into su porting contact with the toe of the jacked s 0e.

For the purpose of tightening the heel band, the under side of the sliding head m (Fig. 9) 'is cut or grooved to receive the end of a toothed lever n, the latter pivoted upon the carriage base for swinging movement 1n a central vertical plane. This toothed lever may be forced forward to clamp the band through movement of the sliding pm n, which bears rearwardly against the finger M, the latter secured to the transverse shaft a passing to the outside of the carriage, where it is provided with a rigidly attached depending lever arm n (Flgs. 9, 10 and 11). The lower end of the lever arm n has secured to it and projecting either side thereof ((Fi s. 5, 10 and 11) the pin n, the outer en of which is secured to the forward end of the tension spring a". The rear end of the spring is pinned to the rear end of the sliding rod 71., the latter receiving near its forward end (Fig. 11) sliding bearing support from the heel carriage base, and having also a slot a in which works the inner end of the pin a. It will be evident that the rod n when forced backwardly, acting through the tension spring n", will draw back the levermfi and cause the closing of the heel band against the shoe counter, continued retracted movement ofthe rod actmg to place the increased tension of the spring upon the clamping of the heel by the band.

To actuate the heel clamping rod n at the proper moment and to the proper extent, the orward end of the rod projects in advance of its bearing in the heel carriage and when the latter is moved into the lasting position shown in Fig. 2, the end of the clamping rod is positioned (Fig. 11) in alinement with and closely adjacent to the uper end of the actuating lever 12 which is pivoted u on the frame A and jointed at its lower en to the horizontal sliding actuator n The latter is slotted to receive a roller guide support n journaled in a transverse frame piece A through which the actuator passes and at its rear end is attached to the spring n by which it tends constantly to be retracted to withdraw the engaging face of the clamp actuating lever from the clamping rod. The opposite end of the actuator slide, however, carries (Figs. 11 and 17) a cam roll n", which is drawn b .the spring 12 into contact with the suita ly formed face of the rotary side cam o. The latter (Figs. 2 and 17 is keyed to the cam sleeve, 0', mounted for rotary movement u on the stationary shaft 0 which latter is journaled in bearings formed by the transverse frame member A and a second transverse end frame member. The cam '0 may be of any suitable formation, the one illustrated having three depressions and three elevations, such that when moved one sixth of a revolution with the carriage and the jacked shoe in lasting position, the cam causes the closing of the open heel band and when moved another sixth of a revolution, causes the release of the then clamped shoe.

Movement of the cam sleeve 0' not only acts to clamp or close the heel band, but also to lift the toe post, and, to this end, in addition to the heel band clam ing cam 0, there is also secured to the cam sleeve (Fi 2 and 13) a lifting cam 0 with the suitab y formed periphery of which is engaged the cam roll 0*, the latter journaled upon a depending lug upon the swinging shelf 2" beneath the toe post. The periphery of the lifting cam (Fig. 13) also has three depresslons and three elevations and the cam 1s so'positioned with reference to the clamping cam 0 that at the same time with movement of the latter to clamp or unclamp the shoe counter, the former raises or lowers respectively the swinging shelf and the toe post and toe rest carried thereby.

To efi'ect power-driven movement of the cam sleeve, the latter has keyed thereto (Figs. 2 and '13) the toothed ratchet wheel 0, the outer edge of which is provided with suitable teeth, herein six in'number, to correspond to the elevations and depressions of the res ect-ive cams and adapted to be engaged ig. 13) by the pawl o pivoted upon an overhangin pawl'support carried by the pawl disk 0'', t e latter bemg loosely mountspring-pressed by the spring 0 into engagement with the teethof the ratchet.

The pawl disk has a radial lug 0, to which is jointed the pawl actuating rod 0* extending downwardly and rearwardly for connection to the short crank o b which it is-operatively connected (Fig. 14 to the counter-shaft p, the latter journaled in bearings formed in the frame at the lower back portionthereof. v r

The outer end of the counter-shaft p has loosely mounted thereon a pulley p, which may be driven bya suitably connected belt or any other source of power, and there are provided suitable clutching devices whereby the driving movement may be'oommunicated at suitable intervals to the counter-shaft ease and thence through the pawl-actuating rod to the ratchet and pawl mechanism of the cam sleeve, causing the ratchet member and cam sleeve to be moved through a distance corresponding to one of the ratchet teeth for each revolution of the counter-shaft. For this pur ose the inner hub of the driving pulley p is toothed and cooperates with a corres ondingly toothed face upon the sliding c utch member the latter being keyed to the counter-she t. The clutch member (Figs. 14-16) is normally withdrawn from engagement with the teeth of the alley by the abutment of the radial lug p aving an inclined cam face, against a 901'- responding face upon the end of the swinging clutch retracting lever p mounted for swinging movement in and out of the path of the radial lpg. The retracting lever 1s secured to a short shaft, the opposite end of which (Figs. 13 and 14) has the crank lever 5 connected to the u wardly and forwardly inclined actuating r0 jointed to one arm of the knee lever (Figs. 1 and 13), the latter pivoted at t 1e front of the machine and suitably formed and positioned to be readily moved by the pressure of the operators knee.

When the knee lever is pressed inwardly the retracting lever is drawn down out of engagement with the clutch lug and the clutch is forced into engagement. with the teeth of the driving pulle by the action of s rings'p seated in the c utch member and abutting against a disk 7)", also ke ed upon the counter-shaft, the actuation of the cam sleeve 0' by the ratchet 0 being continued as long as pressure on the'knee ever is maintained. As soon as pressure upon the knee lever is relieved, the tension spring p (Fig. 13) draws it back into its normal position and throws the clutch retractor upwardly into contact with the periphery of the clutch which is wedged or forced out of engagement with the pulley as soon as the two cam surfaces meet, this, however, not occurring until the countershaft has made at least one complete turn and the ratchet wheel moved through one tooth. The cam sleeve and its actuating parts are caused to stop positively, and Without overthrow due to momentum, by means of a stop 2) (Figs. 13,15 and 16) formed also on the periphery of the clutch to engage with the end of the retractor and thereby bring the counter-shaft p positively to rest, leaving the cam rolls always in the desired position.

' To prevent the momentum of the cam sleeve with its attached members from carrying it beyond the position to which it is moved by each reciprocation of the pawl, the

cam sleeve is also provided with a brake wheel 79 (Figs.'2 and 13) with the periphery of whlch there is frictionally engaged (Fig. 13) a plunger p of rawhide or any other suitable material, pressed against its wheel by a spring 3), the latter l,

ing lever r, the latter pivoted to the frameand carrying at its up er end the horizontal transverse bearing r0 1 1*, which, on de pression of the knee lever, is caused to swim ownwardly and over the projecting ear to the carriage latch, causing the swinging latch member to be withdrawn from the stationary latches b for the release of the carriage as described. This release of-the carriage may be thus, and ordinarily will be directly efiected by the knee movement of the operator, but the knee lever r is caused to overlie (Fig. 1) one end of the knee lever p so that when the former is pressed to reease the carriage, the knee lever p may be,

by the same knee movement, simultaneously swung toeifect the turning of the cam sleeve for the unclamping of the heel band and the dropping of the toe post.

Any suitable means may be employed for returning the carriage to its outward positionafter release, but in the illustrated machine this is automatically eifected immediately upon release by the then tensioned heel c amping spring n. After the carriage is rolled forward to the osition in Fig. 2 and the cam sleeve turned to raise the toe postand tighten the heel band, the spring a is tensioned bythepressure of the camactuated lever a against the abutting heel clamping rod n", th1s acting to seat the carriage with the latches Z against the catches Z. As soon as the latches are lifted b move ment of the knee lever r, the tensione spring kicks the carriage back and away from the cam-operated lever 11 to the outward position shown in Fig. 1.

During the lasting of the shoe it is sometimes desirable to provide additional holddown means and l[ have therefore shown (Figs. 1' and 17) the swinging hold-down arm a, secured to the turning and sliding plunger-rod 8 adapted for vertical move ment in suitably ormed bearings in, the frame the lower end of the rod being attached to a tension rod 8 secured to the foot treadle s, by which the operator may draw the plunger-rod down against the compression of an encircling spring 8*. The outer end of the rod may have any suitable means detachable or otherwise, for engaging with the insole of the lasted shoe and there being V wardl prmecting) foot-piece 8 which when the lever-"r the depending rod t,

- same movement the operator ta e or struck y the foot of the operator wfifact quickly to release the foot lever and to'permit the spring of the hold-down to elevate the latter.

In order that the release of the hold-down may be accomplished at the appropriate time without conscious eifort on t e part of 0 erator, the hold-down ratchet is connected to the carria e releasing mechanism, so that the release 0 the carriage also affects a release of the hold-down. For this purpose 25 th ere. is connected to the carriage releasing w ich, on releasin movement of the releasing lever, is causef both to move upwardly and swing "sli htly to one side. The lower end of the so .5 t

r Figs. 1, 14 and 17 is pivoted and guided y the ratchet pivot pin 8* and has at its bottom the inclined side contacting with a pin t, which is secured to the lower end of-the ratchet. When the carriage releasing lever is raised for the release of the carriage, the depending rod t is both raised and swung to one side about the ratchet p1vot pin and acting against the .pin t swlngs the ratchet away from the catch to cause release of the latter.

The general 0 eration of the machine will be clear from t e foregoing description of its mechanisms. The operator having placed the shoe to be lasted upon the heel post, as indicated in Fig. 1, by turnin the hand wheel k the heel of the shoe is retracted into the heel clamp and elevated againstthe overlapping edge of the wi ers. By the draws the .carriage into the positlon shown in Fig. 2, where it is automatically locked in posltion during the lasting operation by the swing- I ing latch Z. In this position the inverted toe of the shoe isdire ctly over the toe rest ,65 wiping plates. The operator then for an and the toe is in close proximity to the toe I mstant presses the knee lever n throwing in the clutch to cause a single turn of the countor-sleeve and .a partial rotation of the cam shaft, which results in the elevation ofthe toe st and the tightening of the heel band. The liold-down is then into osition over the shoe and forced down by e foot and retardin lever, where it is held by the ratchet. The shoe being then firmly acked and securely held in position the operator pressing upon the foot lever 7' elevates the wiper plates and by manipulating them through the hand lever d" causes them to wi e the leather up and in against the toe an finally over the same in the usual manner. The heel wiping is performed also in the usual manner, the ad ustments of the wiper platesto different inclinations transversely or lengthwise the carriage and the fore and aft adjustment of the toe carriage being effected as may be required to erform the operation. The lastin of the s oe havin been comleted an the lasted upper aving been astened by wiring or tacking, the entire mechanism is restored to its normal position shown in 1 by a single pressure upon the knee lever 1, this acting simultaneously, as described, to drop the toe post, release and return the carriage, unclamp the heel band, drop and throw forward the heel post and release the hold-down.
